Newbies, move on. If you donโt understand why you need such glass, then you donโt need to write reviews. I read here as one wrote that the aperture ratio is mediocre, because the picture is muddy! Yes, he has a depth of field of millimeters, so he called the blur zone soap. Just a poker face. There were 4 fifty dollars: 1.4d, 1.8d, 1.8g and this one. If you need sharpness, take 1.8g, if you need a picture, then this one is a must. Just a masterpiece. I have never done such a three-dimensional image with any lens yet. I recommend it to those who have been ill with sharpness and want to take pictures. This does not mean that it is not sharp, everything is fine. Just 1.8g as a razor, boring technical pixel art. With 50 1.4g, I want to consider and admire every photo. I found the right review where all Nikon fifty dollars are compared in poor lighting conditions, and this lens lost only 58 1.4g, but itโs understandable, different price categories. This one is worth the money.
